Tristan’s half-brother in the Prophecies de Merlin.
Born to King Meliadus of Lyonesse (Meliodas of Liones) and the Queen of Scotland, whom Meliadus had abducted, he was raised by the Lady of the Lake with Lancelot, Bors, and Lionel. When he grew up, he became the Lady of the Lake’s lover.
He convinced the Lady to bring him to Merlin’s tomb, where he wrote down the prophecies spoken by Merlin’s ghost.
